NOAA Marine
Get tide predictions, currents, water levels, and live marine conditions from NOAA stations and buoys.
Connects to NOAA CO-OPS tide and current stations plus NDBC buoys to provide tide predictions, water-level observations, tidal currents, wave conditions, wind, temperature, and ocean profiles for coastal planning and marine activities.
Try asking Muse: "What are the tide times and current speeds for my fishing trip to Seattle this weekend?"

Is it safe to connect?
What Muse can see: It does not ask you to sign in, so it cannot see your accounts. It only sees what Muse sends it from your request.
Before it acts: Read what Muse plans to do before you approve it, and remove the app from Muse when you stop using it.

How to add it to Muse
Not in Muse's Connectors list yet, but Muse can still use it. Copy the request below and paste it into Muse. Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.

Technical details: safety screening, tools, response time and recent checks
Response time at the last check: 589ms. Worked in 100% of checks over 30 days.
Screening · September 25, 2026
Screened, no issues found
Screening looks for known threats and hidden instructions at the time of the check, and runs again weekly and whenever the tool list changes. It cannot see the server's code, so only connect what you need and review what Muse asks to do. How screening works.

noaa_marine_find_stationsFind CO-OPS tide, water-level and current stations and NDBC buoys near a location, by name, or by station ID, returning a unified list with source, data capabilities, coordinates, and — for NDBC — the physical platform class. This is the required first step for resolving a place noaa_marine_get_tide_predictionsHigh and low tide predictions for a CO-OPS tide station over a date range. The default hilo interval returns the time, height, and tide type (H for high, L for low) of each event, while the 6-minute interval returns the detailed tide curve. Most tide stations are subordinate — COnoaa_marine_get_water_levelObserved water level, real-time or historical, for a CO-OPS water-level station, paired with tide predictions for the same period so the residual (observed − predicted) shows storm surge when positive and anomalous drawdown when negative. The interval selects the cadence: 6min (dnoaa_marine_get_monthly_meansVerified monthly means for a CO-OPS water-level station, one row per station-month: the month's highest and lowest water, its tidal datums (MHHW, MHW, MSL, MTL, MLW, MLLW, DTL), tidal ranges (GT, MN, DHQ, DLQ), and lunitidal intervals (HWI, LWI) — the record a sea-level or tidal-noaa_marine_get_currentsTidal current predictions for a CO-OPS current station: max flood and ebb speeds, slack times, and the station's mean flood and ebb bearings. These are forecast predictions from CO-OPS, distinct from noaa_marine_get_current_profile, which returns NDBC observed ocean-current measunoaa_marine_get_conditionsLive marine conditions from an NDBC buoy: wave height, period and direction, wind speed, gust and direction, sea-surface temperature, air temperature, barometric pressure, and dew point. All values are SI units — wind in m/s, wave height in m, pressure in hPa, temperatures in °C noaa_marine_get_current_profileObserved ocean-current depth profile from an NDBC ADCP buoy — the most recent measurement of current speed and direction at each depth bin, returning depth in meters, direction in degrees true (the direction the current flows toward), and speed in cm/s. It is distinct from noaa_mnoaa_marine_get_ocean_observationsLive sub-surface oceanographic observations from an NDBC station's water-quality sensors: at each reported depth, water temperature, conductivity, salinity, dissolved oxygen as both saturation percent and concentration in ppm, chlorophyll, turbidity, pH, and redox potential.

How do I connect NOAA Marine to Muse?
Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use NOAA Marine to help me. It is a free service with an MCP server at https://noaa-marine.caseyjhand.com/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
Is NOAA Marine working right now?
At the last check (September 28, 2026, 07:00 UTC) the endpoint was working, answering in 589ms. Over the last 7 days it answered 100% of health checks. It is checked every 15 minutes.
Is NOAA Marine safe to connect to Muse?
It was screened on September 25, 2026 with the result "screened, no issues found". Screening checks the domain against threat feeds and reads the tools for hidden instructions and requests for passwords or card numbers. It cannot see the server's code, so grant only the access you need.
What can NOAA Marine do in Muse?
It exposes 8 tools, including noaa_marine_find_stations, noaa_marine_get_tide_predictions, noaa_marine_get_water_level, noaa_marine_get_monthly_means. For example, you could ask Muse: "What are the tide times and current speeds for my fishing trip to Seattle this weekend?"
